Looks a little like basswood but it could be a type of Maple. Is the bark kind of stringy if you try to peel it off?
Are you sure this is only one tree? Some of it, including the big round in the first picture and the bark shots, look like Sugar Maple. The stuff with the white sapwood and dark center is Hickory, I'd say.
Okay I'll guess tulip poplar. Basing that totally on the picture of the splits. The second split from the right looks like the bunch I cut about 3 years back. Heavy when green, light as a feather when dry, about 8 months later. The rounds would squirt water as I drove the wedge in. My guess is you let the splits sit a while before you photographed them. I remember thinking how could one found have so many colors.
Im leaning toward maple but not 100 percent. What throws me is some of it was easy to split. Ive never had easy to split maple.
The pic in post # 5 shows me some stringy bark that looks like Basswood. Now that being said, you folks down south and in the midwest have some trees I have never seen and never even heard of. Good luck with the ID, maybe Scotty Overkill can put in his two cents.
